+// Documentation: enclosed is the design of this test.
+//
+// It has been carefully constructed so that it does NOT use other kernel
+// facilities (aside from delay-task) to test that priority inheritance is
+// working, or not, as intended by the configuration.
+//
+// These notes describe the flow of control in one run of the test with the
+// ancillary tasks optionally interspersed. The details of how those extra
+// tasks are or are not allowed to run are not described.
+//
+//
+//
+// The only change in the test that depends on whether there is inheritance or
+// not is the check in thread 2 on "3-ran" and "got it" flags marked ****
+//
+//
+// volatile &c booleans:
+// "got it" = FALSE
+// "3-ran" = FALSE
+// "3-ended" = FALSE
+// "extras"[3] = FALSE

+ * src/jim-aio.c (JimAioHandlerCommand): GCC 4.3.1 pointed out a
+ buffer overrun.
+
+2008-06-17 Anthony Tonizzo <atonizzo@gmail.com>
+
+ Jumbo patch containing many individual patches from a number of
+ different contributors on different days. The ChangeLog entries
+ for all these individual patches are:
+
+ 2007-12-02 Anthony Tonizzo <atonizzo@gmail.com>
+
+ * src/socket.c src/httpd.c: Corrected a bug in
+ cyg_httpd_write_chunked(): Now the CRLF that terminates a chunk is
+ added by the function and not expected to be there already in the
+ data supplied by the user. Modified the function
+ cyg_httpd_end_chunked() so that the flag
+ CYG_HTTPD_MODE_TRANSFER_CHUNKED is always cleared after it
+ terminates. The cyg_httpd_process_request() now loops as many
+ times as the number of full requests received. Renamed header_end
+ to request_end to better reflect its real use, and the fact that
+ the former name was misleading for POST requests (Danny
+ Sade). Changed the function that collects a request: Now the
+ remaining part of an incomplete request is copied back to the
+ beginning of the buffer. This avoids that multiple split headers
+ might creep towards the end of the buffer.
+
+ 2007-11-28 Rene' Nielsen <rbn@vitesse.com> and
+ Anthony Tonizzo <atonizzo@gmail.com>
+
+ * doc/athttpd.sgml: Included Digest (MD5) authentication as fully
+ supported.
+ * cdl/httpd.cdl: Updated the cdl to reflect the fact that MD5
+ authentication is now a fully tested feature, at least on some
+ clients (Thanks to Tad for testing this!)
+ * src/httpd.c: Added the initialization of the global variable
+ cyg_httpd_md5_response. This corrects a security hole that could
+ allow unauthenticated browsers to access pages that require
+ authentication. This required a minor change (switch of variables
+ used) in the authentication code. Added code to avoid a buffer
+ overflow during the parsing of headers for authenticated
+ pages. Clear the CYG_HTTPD_MODE_SEND_HEADER_ONLY at the beginning
+ of any request.
+ * src/auth.c: Removed dead code and made static a bunch of
+ functions and variables.
+ * src/auth.h: The AUTH_STORAGE_BUFFER_LENGTH value is now split
+ into two numbers, one that gives the maximum length of the login
+ phrase and one for the password.
+ * src/socket.c: Added a NULL terminator after each header packet
+ that is received. Now the strstr() is guaranteed to find
+ terminated string.
+
+ 2007-11-27 Tad Artis <ecos@ds3switch.com>
+
+ * src/auth.c: Modified the cyg_httpd_digest_data() and
+ cyg_httpd_digest_skip() functions to support IE7. A careful read
+ of the augmented BNF in RFC2616 indicates that spaces within the
+ elements of the authentication header are optional. The original
+ atHTTPD code incorrectly relied on a space after the comma. Moved
+ the authentication check inside cyg_httpd_process_method() so that
+ each request, regardless of the type, will have to go through
+ authentication.
+
+ 2007-11-26 Tad Artis <ecos@ds3switch.com> and
+ Anthony Tonizzo <atonizzo@gmail.com>
+
+ * src/forms.c: Checked for a null terminator inside
+ cyg_httpd_store_form_variable, so that we do not scan past the end
+ of the packet. Check the form variables for both length and
+ content, to avoid false positives. Modified cyg_httpd_from_hex()
+ to return -1 in case of error.
+ * src/httpd.c: Corrected the strings sent back by the server to
+ challenge the client to an MD5 authentication. Adds a couple of
+ commas to separate the items in the string.
+ * src/http.h:
+ * src/socket.h: Corrected a number of indexes where
+ CYGNUM_FILEIO_NFILE was used instead of the correct
+ CYGPKG_NET_MAXSOCKETS.
+
+2008-03-04 Danny Sade <danny@channelot.com>
+
+ * src/socket.c: put NULL at the end of inbuff on each iteration,
+ preventing strstr from looking at old data beyond inbuffer_len
+
+2007-11-12 Oyvind Harboe <oyvind.harboe@zylin.com>
+2007-11-12 Jonathan Larmour <jifl@eCosCentric.com>
+
+ * doc/athttpd.sgml: added an example of a tcl script.
+ * src/http.c, forms.c: serve cgi requests before file system requests,
+ that way it isn't possible to download the actual cgi/.o script and
+ cgi works even if the http root directory is above the cgi directory.
+ * src/http.c: if only tcl cgi is enabled, cgi requests are now
+ forwarded to tcl
+ * include/jim.h: include file order fix; now compiles again.
+ * doc/athttpd.sgml: Fixed typos in doc. Return value from handler is
+ not used, recommend returning 0 in doc.
+
+2006-12-03 Anthony Tonizzo <atonizzo@gmail.com>
+
+ * cdl/httpd.cdl: Corrected a CDL error in the requirements of
+ CYGOPT_NET_ATHTTPD_USE_FS
+
+2006-11-27 Jonathan Larmour <jifl@eCosCentric.com>
+
+ * cdl/httpd.cdl: Improve CDL dependencies.
+
+2006-11-08 Anthony Tonizzo <atonizzo@gmail.com>
+
+ * doc/athttpd.sgml: Updated to describe lasted changes and corrected
+ minor typos.
+ * src/http.c: Check for "Content-Type" header. This is needed if we
+ want to support parsing form variables in POST requests.
+ * src/jim.c: Updated with latest release from Jim CVS.
+ * src/cgi.c: streamlined cyg_httpd_exec_cgi_tcl(), now uses the 'source'
+ command of tcl to execute a tcl script.
+ * src/forms.c: Modified cyg_handle_method_POST so that the variables in the
+ payload are scanned only if the request has a Content-Type
+ of 'application/x-www-form-urlencoded'
+ * src/jim-aio.c: Added to package. Now tcl has IO functions to access a
+ file system.
+ * include/httpd.h: Added a new mode, CYG_HTTPD_MODE_FORM_DATA which is set
+ when a POST request has a Content-Type of
+ 'application/x-www-form-urlencoded'
+
+2006-10-16 Lars Povlsen <lpovlsen@vitesse.com> and Anthony Tonizzo <atonizzo@gmail.com>
+
+ * cdl/httpd.cdl: add CYGOPT_NET_ATHTTPD_CLOSE_CHUNKED_CONNECTIONS. Default
+ is set to CLOSE, so it is backward compatible with
+ previous versions of the browser.
+ * src/socket.c: cyg_httpd_process_request() uses a loop to collect at least
+ one full frame (til a header terminator is found),
+ cyg_httpd_start_chunked() only close if configured to do so.
+ * src/httpd.c: Overhaul of cyg_httpd_send_error to avoid the use of
+ inbuffer as temporary storage (conflicts with pipelined frames),
+ removed the option to send a page after calling a C language
+ handler
+ * include/httpd.h: Added a new mode, CYG_HTTPD_MODE_NO_CACHE
+
+2006-10-12 Lars Povlsen <lpovlsen@vitesse.com> and Anthony Tonizzo <atonizzo@gmail.com>
+
+ * cdl/httpd.cdl: add CYGNUM_ATHTTPD_SERVER_MAX_POST to limit POST'ed data
+ * include/http.h: Added header_end, post_data fields to httpstate,
+ Added "302 Found" for POST handler redirect (CYG_HTTPD_STATUS_MOVED_TEMPORARILY)
+ * src/forms.c: Fixed variable decoding, fixed large POST processing
+ * src/http.c: Fixed some debug ouptuts, cleanup after POST processing,
+ overhaul of the pipelined requests code which can now
+ handle multiple requests per frame.
+ * src/socket.c: Removed assert for socket write failure, Accumulating receiving

+</itemizedlist>
+
+<para>
+Ecos tables are used extensively throught the server to provide a high degree
+of customization.</para>
+</sect1>
+
+<sect1 id="athttpd-using">
+<title>Starting the server</title>
+<para>
+In order to start the web server, the user needs to call the function:</para>
+
+<programlisting width=72>
+cyg_httpd_start();
+</programlisting>
+
+<para>in the application code. The server initialization code spawns a new
+thread which calls <command>init_all_network_interfaces()</command> to
+initialize the TCP/IP stack and then starts the deamon. The function is safe
+to call multiple times.
+</para>
+</sect1>
+
+<sect1 id="athttpd-mime-types">
+<title>MIME types</title>
+<para>
+The server has an internal table with all the recognized mime types. Each time
+a file or an internal resource is sent out by the server, its extension is
+searched in this table and if a match is found, the associated MIME type is
+then sent out in the header.
+
+The server already provides entries for the following standard file extensions:
+
+'html', 'htm', 'gif', 'jpg', 'css', 'js', 'png'
+
+and the user is responsible for adding any further entry. The syntax for
+adding an entry is the following:</para>
+
+<para><programlisting width=72>
+CYG_HTTPD_MIME_TABLE_ENTRY(entry_label, extension_string, mime_tipe_sting);
+
+entry table : an identifier unique to this entry
+extension string : a string containing the extension for this entry
+type_string : the mime string. The strings for many more mime types
+ is included in a file in the "doc" directory.
+</programlisting></para>
+
+<para>
+The following is an example of how to add the Adobe Portable Document Format
+<command>pdf</command> MIME type to the table:</para>
+
+<para><programlisting width=72>
+CYG_HTTPD_MIME_TABLE_ENTRY(hal_pdf_entry, "pdf", "application/pdf");
+</programlisting></para>
+
+<sect2 id="athttpd-mime-types-chunked">
+<title>MIME Types for Chunked Frames</title>
+<para>
+For chunked frames, which are generally used inside c language callbacks, there
+is no file name to match an extension to, and thus the extension to be used
+must be passed in the <command>cyg_httpd_start_chunked()</command> call. The
+server will then scan the MIME table to find a MIME type to match the extension.
+
+For example, to start a chunked transfer of an <command>html</command> file,
+the following call is used:</para>
+
+<para><programlisting width=72>
+cyg_httpd_start_chunked("html");
+</programlisting></para>
+
+<para>
+In any event, it is the responsibility of the user to make sure that a match to
+all used extensions is found in the table search. Failing this,
+the default MIME type specified in the CYGDAT_NET_ATHTTPD_DEFAULT_MIME_TYPE
+string is returned.</para>
+</sect2>
+</sect1>
+
+<sect1 id="athttpd-callback">
+<title>C language callback functions</title>
+<para>
+The server allows the association of particular URLs to C language callback
+functions. eCos tables are used to define the association between a URL and its
+corresponding callback. The syntax of the macro to add callback entries to
+the table is:
+</para>
+
+<para><programlisting width=72>
+CYG_HTTPD_HANDLER_TABLE_ENTRY(entry_label, url_string, callback);
+
+entry table : an identifier unique to this entry.
+url_string : a string with the extension url that will be appended to the
+ default directory.
+callback : a function with a prototype:
+ cyg_int32 callback_function(CYG_HTTPD_STATE*);
+ Return value is ignored - just return 0.
+</programlisting></para>
+
+<para>
+<command>CYG_HTTPD_STATE*</command> is a pointer to a structure that
+contains, among others, a buffer (outbuffer) that can be used to send data
+out. The definitions of the structure is in http.h.</para>
+
+<para>
+The following is an example of how to add a callback to a function myForm()
+whenever the URL /myform.cgi is requested:
+</para>
+
+<programlisting width=72>
+CYG_HTTPD_HANDLER_TABLE_ENTRY(hal_cb_entry, "/myform.cgi", myForm);
+</programlisting>
+
+<para>
+and somewhere in the source tree there is a function:</para>
+
+<programlisting>
+cyg_int32 myForm(CYG_HTTPD_STATE* p)
+{
+ cyg_httpd_start_chunked("html");
+ strcpy(p->outbuffer, "eCos Web Server");
+ cyg_httpd_write_chunked(p->outbuffer, strlen(p->outbuffer))
+ cyg_httpd_end_chunked();
+}
+</programlisting>
+
+<para>This function also shows the correct method of using the chunked frames
+API inside a c language callback and also shows the use of outbuffer to
+collect data to send out.</para>
+
+<para>Chunked frames are useful when the size of the frame is not known upfront.
+In this case it possible to send a response in chunks of various sizes, and
+terminate it with a null chunk (See RFC 2616 for details). To use chunked
+frames, the <command>cyg_httpd_start_chunked()</command> function is used.
+The prototype is the following:</para>
+
+<programlisting>
+ssize_t cyg_httpd_start_chunked(char *);
+</programlisting>
+
+<para>The only parameter is the <command>extension</command> to use in the
+search for the MIME type. For most files this will be "html" or "htm" and
+it will be searched in the MIME table for an approriate MIME type that will
+be sent along in the header. The function returns the number of bytes sent
+out.</para>
+
+<para>The chunked frame must be terminated by a call to
+<command>cyg_httpd_end_chunked()</command>:</para>
+
+<programlisting>
+void cyg_httpd_end_chunked()(void);
+</programlisting>
+
+<para>In between these two calls, the user can call the function
+<command>cyg_httpd_write_chunked()</command> to send out data any number of
+times. It is important that <command>cyg_httpd_write_chunked()</command> be
+the only function used to send data out for chunked frames. This
+guarantees that proper formatting of the response is respected.
+The prototype for the function is:</para>
+
+<programlisting>
+ssize_t cyg_httpd_write_chunked(char* p, int len);
+</programlisting>
+
+<para>The 'char*' points to the data to send out, the 'int' is the length of the
+data to send.</para>
+
+<para>In the case in which the size of the data is known upfront, the
+callback can instead create the header with a call to
+<command>cyg_httpd_create_std_header()</command> with the following
+prototype:</para>
+
+<programlisting>
+void cyg_httpd_create_std_header(char *ext, int len);
+
+extension : the extension used in the search of the MIME type
+len : length of the data to send out
+</programlisting>
+
+<para>and use
+<command>cyg_httpd_write()</command> to send data out to the client. The
+ prototype of <command>cyg_httpd_write()</command> is the same as
+<command>cyg_httpd_write_chunked()</command></para></sect1>
+
+<sect1 id="athttpd-cgi">
+<title>CGI</title>
+<para>
+The web server allows writing of pseudo-CGI programs. This is helpful in order
+to modify the functionality of the server without having to recompile it and
+reflash it.</para>
+
+<para>One way to implement CGI is, of course, the C language callback mechanism
+described above: This assumes, of course, that all the callbacks are written
+by compile time and cannot be modified later on. Another way to perform the
+same functionality is the use of a library in the form of an object file.
+These object files reside in the file system and are loaded, executed and
+unloaded on demand.</para>
+
+<para>Yet a third way is the use of a scripting language. Since full fledged
+implementation of the most popular scripting languages such as Python or Perl
+are too large for most embedded systems, a slim down implementation of tcl
+was chosen for this server. Most of the tcl functionality is still there,
+and makes writing cgi a lot easier.</para>
+
+<para>In order to limit the footprint of the operating system support for both
+the objloader and the tcl script for dealing with cgi files can be
+independently selected out. Tcl support in particular increases the memory
+requirements considerably.

+<sect2 id="athttpd-cgi-objloader">
+<title>CGI via objloader</title>
+<para>
+In order to use the cgi mechanism the CYGPKG_OBJLOADER must be included
+when building the operating system. This will enable the proper option in the
+configuration tool and if selected, the necessary code will be compiled
+in the eCos kernel. The user will then have to compile the necessary libraries
+and place them in the file system under a directory defined by
+CYGDAT_NET_ATHTTPD_SERVEROPT_CGIDIR.
+When a request is made, the web server checks if the root directory of the
+requested URL is inside the CYGDAT_NET_ATHTTPD_SERVEROPT_CGIDIR directory.
+If so, the server assumes that the user requested a cgi file and looks into the
+directory to see if a library by the same name is present, and if so load it
+and tries to execute a function inside the library with the following prototype:
+</para>
+
+<programlisting width=72>void exec_cgi(CYG_HTTPD_STATE *)
+</programlisting>
+
+<para>
+The pointer <command>CYG_HTTPD_STATE*</command> gives access to the socket
+data: The user will use this pointer to access the 'outbuffer' and use it to
+copy data to send data out.
+</para>
+
+<para>
+When using the OBJLOADER package within the HTTP server a number of functions
+are automatically added to the externals table of the OBJLOADER package. These
+functions are likely to be used inside the library and the relocator need to
+have a pointer to them. In order to add more functions, see the OBJLOADER
+documentation. The complete list of the functions automatically added is:

+minimal, and it is only useful for very simple applications, but it is an
+excellent starting point for further development.</para>
+
+<para>In order for the scripting language to be useful, it has to access
+the form variables passed on during the GET or POST request. Because of
+this, all form variables registered with the CYG_HTTPD_FVAR_TABLE_ENTRY()
+macro are accessible via tcl. For example, if we have registered a
+form variable called foo, and during the GET request we are defining foo
+as being "1":</para>
+
+<programlisting width=72>GET /myForm.cgi?foo=1</programlisting>
+
+<para>then tcl will be able to access the variable foo as $foo. The data
+in the body of a POST request is also accessible through the use of the variable
+$post_data. This is useful if the data is not in "multipart/form-data"
+and tcl has to perform any type of processing on the data itself.</para>

+<title>Authentication</title>
+<para>
+The server supports both Basic (base64) and Digest (MD5) authentication,
+although they have not been tested with all clients. In this implementation,
+the contents of certain directories of the file system can be protected, such
+that the user will be required to issue a username/password to access the
+content of the directory.</para>
+
+<para>To protect a directory with a basic authentication, there is a
+specific macro:</para>
+
+<programlisting>
+CYG_HTTPD_AUTH_TABLE_ENTRY(entry, path, domain, un, pw, mode)
+
+entry : an identifier unique to this entry.
+path : the path to the directory whose content must be
+ authenticated before it is sent out
+domain : a domain identifier for this directory.
+un : username for authentication
+pw : password for authentication
+mode : CYG_HTTPD_AUTH_BASIC for base64 encoding or
+ CYG_HTTPD_AUTH_DIGEST for MD5 encoding
+</programlisting>
+
+<para>for example, to require basic authentication of the content of directory
+"/ecos/" with a username of "foo" and password "bar", the following is used:
+</para>
+
+<programlisting>
+CYG_HTTPD_AUTH_TABLE_ENTRY(hal_domain1_entry, \
+ "/ecos/", "ecos_domain", \
+ "foo", "bar", \
+ CYG_HTTPD_AUTH_BASIC);
+</programlisting>
+
+<para>Any request for a file in the directory /ecos/ will now trigger a
+credential check. These credentials, once provided, are automatically sent by
+the client for every request within the particular domain.</para>
+
+<para>It must be noticed that the path name set in the macro is relative to the
+HTML document directory, CYGDAT_NET_HTTPD_SERVEROPT_HTMLDIR and it is the
+first part of the path provided by the client request (including the leading
+slash).</para>
+
+<para>In order to reduce the footprint of the server, authentication
+is not enabled by default, and so the option CYGOPT_NET_ATHTTPD_USE_AUTH must
+be used to enable support for basic and digest authentication.</para>
+
+<para>The MD5 digest authentication support is implemented using the RSA
+Data Security, Inc. MD5 Message-Digest Algorithm. Derivative works with
+MD5 digest authentication included must be identified as "derived from the
+RSA Data Security, Inc. MD5 Message-Digest Algorithm" in all material
+mentioning or referencing the derived work. See the file md5.c within this
+package for license details.</para>

+
+<sect1 id="athttpd-dirlist">
+<title>Directory Listing</title>
+
+<para>If the user issues a "GET" request with a URL terminating in a slash, the
+server will try to locate one of the following index files in the directory,
+choosing one in the following order:</para>
+
+<itemizedlist>
+ <listitem><para>index.html</para></listitem>
+ <listitem><para>index.htm</para></listitem>
+ <listitem><para>default.html</para></listitem>

+</itemizedlist>
+
+<para>If any of these files is found, its contents are sent back
+to the client. If no such file is found the server uses the user-provided
+index file name (if any is specified with the CYGDAT_NET_ATHTTPD_ALTERNATE_HOME
+setting. Failing all this a directory listing is sent.</para>
+
+<para>Trailing slash redirection for directory names is supported.</para>
+
+<para>In order to reduce the footprint of the server, directory listing can
+be disabled by unchecking CYGOPT_NET_ATHTTPD_USE_DIRLIST. The savings are
+substantial since directory listing also makes use of a few internal
+resources (gif files) which are also compiled out.</para>
+</sect1>
+
+<sect1 id="athttpd-formvars">
+<title>Form Variables</title>
+
+<para>The server will automatically try to parse form variables when a form is
+submitted in the following cases:
+
+<itemizedlist>
+ <listitem><para>In a GET request, when the URL is followed by a question
+ mark sign</para></listitem>
+ <listitem><para>In a POST request, when the the 'Content-Type' header line
+ is set to 'application/x-www-form-urlencoded'</para></listitem>
+</itemizedlist>
+
+The variable names to look for during the parsing are held in
+an eCos table. In order to take advantage of this feature, the user first
+adds the variable names to the table, which also requires providing a buffer
+where the parsed value will eventually be stored. The values will then be
+available in the buffers during the processing of the request, presumably in
+the body of a c language callback or CGI script.</para>
+
+<para>For example, if the user wants two form variables, "foo" and "bar", to
+be parsed automatically, those variable names must be added to the table
+with the following macro:</para>
+
+<programlisting>
+CYG_HTTPD_FVAR_TABLE_ENTRY(entry, name, buffp, bufflen)
+
+entry : an identifier unique to this entry.
+name : name of the form variable
+buffp : a pointer to a buffer of characters where to store the value
+ of the form variable.
+bufflen : The length of the buffer. Must include a trailing string
+ terminator.
+</programlisting>
+
+<para>or, in the specific instance mentioned above:</para>
+
+<programlisting>
+#define HTML_VAR_LEN 20
+char var_foo[HTML_VAR_LEN];
+char var_bar[HTML_VAR_LEN];
+CYG_HTTPD_FVAR_TABLE_ENTRY(hal_form_entry_foo, "foo", var_foo, HTML_VAR_LEN);
+CYG_HTTPD_FVAR_TABLE_ENTRY(hal_form_entry_bar, "bar", var_bar, HTML_VAR_LEN);
+</programlisting>
+
+<para>and after the GET or POST submissions, the list will contain the value
+for "foo" and "bar" (if they were found in the form data.) It is the
+responsability of the user to make sure that the buffer is large enough
+to hold all the data parsed (including the string terminator). The parser will
+write only up to the length of the buffer minus one (the last being the
+terminator) and discard any additional data.</para>
+
+<para>The values parsed are likely going to be used in c language callback, or
+in CGI files. In a c language callback the user can directly access the pointers
+of individual variables for further processing, keeping in mind that the parsing
+always result in a string of characters to be produced, and any conversion
+(e.g. from strings to integer) must be performed within the callback. In
+a TCL script the user can just access a variable by its name. For example,
+in the case of the variables 'foo' and 'bar' shown above, it is possible
+to do something like 'write_chunked "You wrote $foo". The data that was sent in
+the body of a POST request is accessible in through a variable called
+'post_data'. In CGI functions
+implemented using the objloader the pointers to the
+variables cannot be accessed directly, since the library will likely not
+know their location in memory. The proper way to access them is by using the
+cyg_httpd_find_form_variable() function from within the library:</para>
+
+<programlisting>
+char* cyg_httpd_find_form_variable(char* name)
+
+name : name of the form variable to look up
+
+returns a pointer to the buffer, or 0 if the variable was not found.
+</programlisting>
+
+<para>When using the OBJLOADER package within the web server, an entry
+for the cyg_httpd_find_form_variable() function is automatically added to the
+externals table the OBJLOADER for relocation. See the OBLOADER paragraph of
+the ATHTTP user's guide for the full list of the exported functions.</para>
+
+<para>In order to avoid stale data, all the buffers in the table are cleared
+before running the parser and thus any variable in the list that was not
+assigned a new value dureing the request will be an empty string.</para>
+</sect1>
+
+<sect1 id="athttpd-ires">
+<title>Internal Resources</title>
+
+<para>When the server does not use a file system the user must be responsible
+to provide a C language callback function for each URL that will be
+requested by the client. This means locating the data and sending it out
+using either <command>cyg_httpd_write()</command> or
+<command>cyg_httpd_write_chunked()</command>.</para>
+
+<para>In order to simplify this process the server allows registering
+any number of URLs as internal resources, by providing the URL name, the
+pointer to the resource data and its size. When a URL is requested the
+server will look it up among all internal resources, and if found, it
+will send out the resource.</para>
+
+<para>Internal resource can also be used along with a file system. In this
+case the file system is searched first, and if a file is found, it it
+sent. If a file is not found, the internal resources are searched and
+if a match if found it is sent.</para>
+
+<para>The drawback of this approach is, of course, that all these
+resources are going to add to the size of the operating system image, and thus
+it should be used only when memory is not a major constraint of the
+design.</para>
+
+<para>As always, to provide this type of customization, ecos tables are used.
+The format for adding a new resource to the internal table is the following:
+</para>
+
+<programlisting>
+CYG_HTTPD_IRES_TABLE_ENTRY(entry, name, buffp, len)
+
+entry : an identifier unique to this entry.
+name : name of the URL including leading '/'
+buffp : a pointer to a buffer of characters where to store the value
+ of the form variable.
+len : size of the array
+</programlisting>
+
+<para>As an example, if the user wants to provide his own web page by
+hardcoding it in the application code, here is how he would do it:</para>
+
+<programlisting>
+#define MY_OWN_HOME_PAGE "eCos RTOS"
+CYG_HTTPD_IRES_TABLE_ENTRY(cyg_httpd_ires_home, \
+ "/index.html", \
+ MY_OWN_HOME_PAGE, \
+ 9);
+</programlisting>
+
+<para>The extension of the file name determines the MIME type to be used for
+internal resources.</para>
+
+<para>When using directory listing you are implicitly making use of internal
+resources. The small icons that appear to the left of file names and
+directories are internal resources. Unchecking CYGOPT_NET_HTTP_USE_DIRLIST
+will prevent the addition of these files.</para>
+
+<para>In order to use internal resources, a generic file must first be
+turned into a c language array, which is then compiled in the application
+code. To create this array you can use the tcl script that comes with the
+ecos distribution at packages/fs/rom/current/support/file2.tcl.</para>

+ * ScriptToken structures, with an associated command structure array.
+ * The command structure is a pre-computed representation of the
+ * command length and arguments structure as a simple liner array
+ * of integers.
+ *
+ * For example the script:
+ *
+ * puts hello
+ * set $i $x$y [foo]BAR
+ *
+ * will produce a ScriptObj with the following Tokens:
+ *
+ * ESC puts
+ * SEP
+ * ESC hello
+ * EOL
+ * ESC set
+ * EOL
+ * VAR i
+ * SEP
+ * VAR x
+ * VAR y
+ * SEP
+ * CMD foo
+ * ESC BAR
+ * EOL
+ *
+ * This is a description of the tokens, separators, and of lines.
+ * The command structure instead represents the number of arguments
+ * of every command, followed by the tokens of which every argument
+ * is composed. So for the example script, the cmdstruct array will
+ * contain:
+ *
+ * 2 1 1 4 1 1 2 2
+ *
+ * Because "puts hello" has two args (2), composed of single tokens (1 1)
+ * While "set $i $x$y [foo]BAR" has four (4) args, the first two
+ * composed of single tokens (1 1) and the last two of double tokens
+ * (2 2).
+ *
+ * The precomputation of the command structure makes Jim_Eval() faster,
+ * and simpler because there aren't dynamic lengths / allocations.
+ *
+ * -- {expand} handling --
+ *
+ * Expand is handled in a special way. When a command
+ * contains at least an argument with the {expand} prefix,
+ * the command structure presents a -1 before the integer
+ * describing the number of arguments. This is used in order
+ * to send the command exection to a different path in case
+ * of {expand} and guarantee a fast path for the more common
+ * case. Also, the integers describing the number of tokens
+ * are expressed with negative sign, to allow for fast check
+ * of what's an {expand}-prefixed argument and what not.
+ *
+ * For example the command:
+ *
+ * list {expand}{1 2}
+ *
+ * Will produce the following cmdstruct array:
+ *
+ * -1 2 1 -2
+ *
+ * -- the substFlags field of the structure --
+ *
+ * The scriptObj structure is used to represent both "script" objects
+ * and "subst" objects. In the second case, the cmdStruct related
+ * fields are not used at all, but there is an additional field used
+ * that is 'substFlags': this represents the flags used to turn
+ * the string into the intenral representation used to perform the
+ * substitution. If this flags are not what the application requires
+ * the scriptObj is created again. For example the script:
+ *
+ * subst -nocommands $string
+ * subst -novariables $string
+ *
+ * Will recreate the internal representation of the $string object
+ * two times.

+2000-11-10 Hugo Tyson <hmt@redhat.com>
+
+ * tests/autohost.inl (autohost_init): Call the memory checking
+ init and finalization functions in the appropriate places.
+
+ * tests/memcheck.inl (RATIO): New file; check for mbuf &c leaks
+ (if the API is defined in network.h, so it it'll work with the 144
+ tarball). We allow either as much again or 15% of memory to be
+ used at the end of the test, for each of the 3 memory regions the
+ stack uses.
+
+ * tests/floodpingmux.c (net_test): Don't print out mbuf &c usage,
+ leave it up to the memory checking subsystem.
+
+2000-11-10 Hugo Tyson <hmt@redhat.com>
+
+ * host/obey.sh: Handle the new case of doing snmpwalk and
+ snmpstatus to the target. (SNMP_WALK)
+
+ * cdl/net_autotest.cdl: Build the new tests.
+
+ * host/snmpwalk.sh: New file: snmpwalk the target's public MIB and
+ check target status for the timeout. Much like the other cases.
+
+ * tests/snmpwalk.c: New file: do one snmpwalk session on each
+ interface.
+
+ * tests/snmpmulti.c: New file: ditto, 3 sessions per i/f.
+

+2000-11-09 Hugo Tyson <hmt@redhat.com>
+
+ * host/obey.sh: Handle the new case of flood pinging the
+ target. (FLOOD_PING)
+
+ * host/floodping.sh: New file: flood ping the target, with a
+ variable active/sleep ratio so that we can use this to perturb
+ other tests also. An suid executable "./_suping" is needed to be
+ able to flood ping automatically.
+
+ * cdl/net_autotest.cdl: Build the two new tests.
+
+ * tests/floodping.c: New file: ask the host to flood ping me, for
+ 5 minutes in the usual manner.
+
+ * tests/floodpingmux.c: New file: as floodping.c and the target
+ floods the host in turn also.
+
+ * host/makefile: Build _suping: it must be set uid &c manually.
+
+ * host/_suping.c: New file: a tiny su root program to run ping

+ the target.
+
+2000-11-08 Hugo Tyson <hmt@redhat.com>
+
+ * tests/autohost.inl (XFAIL): Detect the configuration that means
+ simulated unreliable network is enabled. Send the XFAIL parameter
+ to the network testing server if so. Also do not check for the
+ count of pass messages required in the autohost_end() routine; we
+ expect them to go missing and/or there to be failures per se.

+ parameter to indicate simulated unreliable network is enabled.
+
+ * host/tftpget.sh (XFAIL):

+ the interleaved status messages.
+
+ * host/sendack.sh (XFAIL): Try less zealously and moan less loudly
+ if failure is expected.

+
+2000-10-24 Hugo Tyson <hmt@redhat.com>
+
+ * tests/tftp_serv.inl: New file, the guts of both tftp_serv_get.c
+ and tftp_serv_put.c removed to here, so that a number of tests can
+ be created to hit the server with different sizes of datafile.
+ This is the easiest way to test lots of different filesizes and

+
+ * host/tmpfile.c (main): New file: builds to a simple executable
+ that makes a scratch file full of random data of the length

+ though the testcase doesn't use this yet.
+
+ * tests/tftp_serv_put.c (do_tftp_tests):

+
+Host Software for Automated Network Testing for eCos
+====================================================
+
+Hugo Tyson, Red Hat, Cambridge UK, 2000-10-20
+
+
+What Host Software?
+-------------------
+
+This note refers to the package CYGPKG_NET_AUTOTEST which lives in
+packages/net/autotest in the eCos repository.
+
+It contains, amongst other things, some software to run a "network testing
+server" which eCos network test cases (from the same package) use to test
+the network stack.
+
+The reason such a server is needed is simple: testing the eCos network
+stack involves an external, standard, computer _doing_things_to_ the target
+board as well as having the target board's test program do things itself.
+
+For example, one test case (in the main network package, net/tcpip) to test
+TFTP will get a file from a server using TFTP and put the data to another
+file on the server using TFTP. This tests the ability of the eCos TCPIP
+stack to act as a TFTP client. But it does not test the eCos TCPIP stack's
+TFTP server at all. To do that an external agent must act as client -
+using the standard tftp(1) app on linux, for example - to put and get data
+to and from an eCos testcase running on the target, offering a TFTP server.
+
+
+Quick Start Guide
+-----------------
+
+Set up your LINUX machine to serve DHCP to the target you want to test;
+ensure that any 10.0.0.x addresses used are given a class C (/24) netmask.
+Provide a genuine gateway to the internet via some route; the routing tests
+expect to ping www.cygnus.com! Also let it have the normal networking apps
+(tftp, ftp, ping) and servers (tftpd, ftpd) available, plus the SNMP
+package from UCD: snmpwalk and snmpstatus and standard MIBs.
+
+Make sure it is on on the same network(s) as the target you want to test.
+
+Set up aliases for loopback interface on the servers: on server for eth0 on
+the target, add an alias for 10.0.3.1/24. For eth1, 10.0.4.1/24.
+
+With a checked-out eCos source tree, change directory into either
+packages/net/autotest/current/host or a copy of it, and type make.
+
+Follow the printed instruction to change the simple executable "./_suping"
+to su root execution. You will need to become root temporarily to do this.
+
+Make sure . is on your path and type "awaitorder | obey.sh" to run the
+server; it prints info about messages it receives and sends.
+
+The test server is now running. You can now run test built from the
+CYGPKG_NET_AUTOTEST package (packages/net/autotest) on your target and they
+will talk to this host test server.
+
+
+Categories of Tests
+-------------------
+
+ o Host passive
+
+ The host is server, the eCos test case is the proactive client.
+
+ Such tests use the host to talk to, where the eCos testcase is the
+ client, and the host is the server. The network testing server is
+ not involved in these tests, but other servers which must be set up
+ there are used.
+
+ o Host proactive
+
+ The host is client to the eCos server.
+
+ The target board running eCos is the server, the host must run
+ scripts to do thing to it and report success or otherwise over the
+ net. The eCos test case typically starts a server, issues order
+ about how to test it, then sleeps for a time until the test is
+ deemed complete.
+
+
+Building the Network Testing Server
+-----------------------------------
+
+Cd into either packages/net/autotest/current/host or a copy of it, and type
+make. The standard makefile just compiles ./awaitorder.c into ./awaitorder
+the executable that waits for a request from a testcase and prints it to
+its stdout. It also builds some other utilities that are used by the test
+scripts, for example ./tmpfile from ./tmpfile.c - this just creates a file
+of random data for passing back and forth. It also builds _suping: make
+sure this is suid-root to be able to flood-ping the target.
+
+
+Running the Network Testing Server
+----------------------------------
+
+Make sure "." is on your path, early enough, then
+
+ awaitorder | obey.sh
+
+This is all you need to do to run the testing server.
+
+
+"./awaitorder" just waits for a connection on TCP port 9980 and prints what
+it receives. For example, to test it:
+
+ % telnet masala 9980
+ you type ---> Eggs, bacon, beans, mushrooms, toast and coffee
+ Acknowledged
+ Connection closed by foreign host.
+ %
+
+and awaitorder will print as follows:
+
+ % awaitorder
+ awaitorder: connection from 172.16.19.13:3739
+ ORDERS: Eggs, bacon, beans, mushrooms, toast and coffee
+
+and continue waiting for the next order.
+
+
+"./obey.sh" does rather more. It assumes that its stdin is connected to a
+source of orders, and it expects that lines of input will look like this:
+
+ ORDERS: TFTP_SERV_GET 10.16.19.171 300
+
+or more generally
+
+ "ORDERS:" [XFAIL] <order> <target IP> <extra params...>
+
+The set of valid orders (TFTP_SERV_GET, TFTP_SERV_PUT ...) will expand with
+time as we add more tests.
+
+Having checked that an order looks generally valid, and set up some
+environment, it then switches on the order to execute a test script to do
+what the testcase that sent the order wants. The extra params are given to
+the test script. The test script is invoked in background, so that several
+sessions can be running at once to hit the target board hard, or of course
+one network testing server can be servicing several target boards running
+different testcases all at once. After the test script is launched,
+obey.sh just loops back to reading an input line, to get the next order.
+
+"XFAIL" in parameter 1 means the target is configured to simulate network
+unreliability, or otherwise be uncooperative. It is passed both to the
+individual testing scripts and to the system for returning status messages
+to the test target.
+
+This structure is designed to allow separate development and testing of the
+individual parts of the network testing server and also of new testcases;
+the eCos testcase and its test script can be developed on your desk without
+running the network test server - you only need to knit them all together
+at the end by adding a simple clause to obey.sh to invoke the test script
+automatically.
+
+
+Test Script Environment
+-----------------------
+
+There is some IO redirection nastiness in obey.sh to separate errors from
+good status from status to return to the eCos testcase and so on.
+
+awaitorder takes care to issue complaints to stderr, whilst obviously its
+stdout is piped in to obey.sh
+
+obey.sh takes care to issue problem reports to stderr, and mere commentary
+to stdout; neither is paricularly verbose right now, so there's no need to
+so anything special.
+
+Individual test scripts are invoked as follows. Stdout is directed to a
+logfile named uniquely and for the test in question, according the the
+variable $LG. Stderr is piped to an acknowledgement agent, by default
+"./sendack.sh", which is invoked with the target address as its argument.
+This returns status messages from the host testing script to the eCos
+testcase via TCP port 9990.
+
+Let's look at the two example switch cases for the TFTP tests. There are
+two to mostly put versus mostly get files with the eCos TFTP server.
+
+ # Now the main swicth that runs the test script: this is where
+ # new testcases are added:
+ case $TEST in
+
+ TFTP_SERV_GET)
+ tftpget.sh $TARGET $WF/tftpget.$unique ${PARAMS[@]} \
+ 2>&1 >$LG/tftpget.$unique | $SENDACK $TARGET & ;;
+
+ TFTP_SERV_PUT)
+ tftpput.sh $TARGET $WF/tftpput.$unique ${PARAMS[@]} \
+ 2>&1 >$LG/tftpput.$unique | $SENDACK $TARGET & ;;
+
+OK, this is horrid. But breaking up one example:
+
+this first part is the invokation of the script:
+
+ tftpput.sh $TARGET $WF/tftpput.$unique ${PARAMS[@]}
+
+its arguments are
+
+ tftpput.sh <target IP> <temporary file> <timeout> <filesize>
+
+ o <target IP> is $TARGET, from the original order.
+
+ o obey.sh has invented <temporary file> with a unique id, in the workfiles
+ directory, $WF. It will typically be "/tmp/auto/wf/tftpput.1138". In
+ this example, the test script will make files called
+ "/tmp/auto/wf/tftpput.1138.src" and "/tmp/auto/wf/tftpput.1138.tmp" to
+ play with; one is created by the tmpfile program, the other read back
+ from the TFTP server.
+
+ o <timeout> is part of the extra params supplied by the eCos testcase,
+ which in this case will serve TFTP for about 5 minutes, so it tells the
+ test script to diddle it for about 5 minutes too.
+
+ o <filesize> is another param supplied by the eCos testcase, which tells
+ the script to create a testfile of a particular size to exercise edge
+ conditions wrt the blocksize.
+
+The second part of the example is the IO redirection and backgrounding:
+
+ 2>&1 >$LG/tftpput.$unique | $SENDACK $XFAIL $TARGET & ;;
+
+This sets the script's fd2 to a copy of its stdout, then sets its stdout to
+go to the logfile, typically "/tmp/auto/log/tftpput.1138", then pipes the
+original stdout which now occupies fd2 into $SENDACK, the acknowledgement
+agent, which is itself invoked with the target's IP address and optionally
+XFAIL to tell it not to be so upset if it fails to return the result. The
+whole thing is run in background by the "&" and the ";;" is the end of this
+case within the switch statement. Phew!
+
+More briefly, the test script's stdout goes into the logfile and the test
+script's stderr goes into $SENDACK (./sendack.sh) and thence to the
+testcase.
+
+
+Typical Output
+--------------
+
+This is the output from awaitorder | obey.sh from running just one eCos
+testcase, which requests 3 simultaneous TFTP sessions for 5 minutes:

+
+
+Individual Host Testing Scripts
+-------------------------------
+
+The params and invocation of these is entirely a matter of agreement
+between the eCos testcase and the test script. A new case arm in the
+obey.sh switch statement must be written for any new testcase, so the
+script's invocation is not prescribed in any way.
+
+For the sake of easier separate development of testcases, it would be
+better to follow the pattern of the other testcases, also for consistency
+and comprehensibility. Here are some guidelines and requirements, but
+first some assumptions:
+
+ o One test script "does things to" one target board, and more specifically
+ one target IP address. If you want several things done to your target
+ board at once, invoke several scripts at once - all on the same IP
+ address if you want, that's fine.
+
+ o The test script may need to be told that the target network stack is
+ configured to simulate network unreliability, so the test script should
+ not expect perfect communications. Eg. weaker protocols will in fact
+ fail - the point of the test is verify that the target does not hang or
+ crash or assert-fail and so on; host side network failures within the
+ script are unimportant. Otherwise, the test script should expect
+ correct operation in the operations it performs.
+
+ o The network test server can serve testing to many eCos target boards at
+ once. Therefore any particular test script can be invoked several times
+ at once to deal with different target boards, if they happen at random
+ to run the same testcase at the same time as each other. Therefore a
+ test script should only use temporary files which are uniquely named per
+ invocation.
+
+These lead to requirements and guidelines:
+
+ o Take the flag XFAIL optionally as the first argument, if it is XFAIL
+ shift to get the other arguments.
+
+ o Take the target IP address as the next argument; it's an obvious place
+ for it and you'll certainly need it anyhow.
+
+ o For workfiles, have obey.sh supply a parameter to name such files
+ uniquely. Use a full pathname. Include the test type also, for example
+ "/tmp/auto/wf/tftpput.1138" identifies the file as belonging to the
+ tftpput testcase. Make required workfiles be second and subsequent
+ arguments.
+
+ o Further arguments which are arbitrary and passed from the testcase
+ should be last, and passed all together. It's not convenient in the
+ shell to split out words 2 through the end from an array if you already
+ quoted word one elsewhere, so instead put all the extras together as in
+ ${PARAMS[@]} in the tftpput.sh invocation discussed above.
+
+
+Other Environment
+-----------------
+
+ o DHCP
+
+Set up DHCP to support the target board - it's the easiest way.
+
+The tests know which server to talk to by looking in the server ID field of
+the bootp information record; if DHCP or BOOTP is used, this will be the
+server that served it. It is also possible to set up the stack with static
+initialization of that field - if you do this, make sure it points to a
+machine that is running the network test server.
+
+Setting up the server to serve DHCP to the target boards only is easy;
+keeping other DHCP servers, who offer dynamic addresses to any new net
+presence, from offering service to them requires a little trick. A dynamic
+server should be set up to supply a static address to the target board's
+MAC address, with the additional key: "deny booting;". This does nothing
+malicious, but it lets the server recognize the target board and ignore it.
+
+This ensures that the network test server machine "wins" the race to set up
+the target, and so ensures that the test talks to the network test server
+rather than trying to talk to a global DHCP server.
+
+
+ o /tmp clearance
+
+The ongoing testing fills /tmp with log files and work files. The logs
+will likely not be very large, but the work files could be a few Mb per
+test run.
+
+A cron job to remove everything older than an hour, or some such might be
+useful; or if the machine can stand it, just wipe /tmp/auto every night.
+
+
+ o Ping!
+
+The tests will expect to ping (and flood ping) the server; it should be
+allowed to do this back. An suid executable (CARE!) is needed to enable
+this. "./_suping" is built by the host makefile: make it be suid root.
+It is a trivial app that execs ping after setting the effective UID to
+root. This is necessary because ping is an suid-root executable anyway, to
+be able to get at raw sockets; it checks the effective UID to decide
+whether to permit flood pinging; we need this for the flood tests floodping
+and floodpingmux.
+
+
+ o Network aliases in the loopback interface
+
+The routing tests require a network setup like this:
+
+ 10.0.3.1 A.B.C.D A.B.C.E N.M.O.P N.M.O.Q 10.0.4.1
+ -------- Box1 ----------------- target ----------------- Box2 --------
+
+
+Optionally with 10.0.3 and 10.0.4 being real networks, with other stations
+on them; addresses 10.0.x.99 are also pinged. Alternatively, 10.0.3 and
+10.0.4 can be aliases for the loopback device in Box1 and Box2 (which may
+be the same box really). A typical setup might really look like:
+
+ HOST: eth0 172.16.19.13 ------ 172.16.19.171 eth0 on TARGET
+ HOST: eth1 10.16.19.13 -------- 10.16.19.171 eth1 on TARGET
+ HOST: lo:0 10.0.3.1
+ HOST: lo:1 10.0.4.1
+
+with all netmasks being /24 (255.255.255.0).
+
+This means that the target can only ping addresses 10.0.3.x and 10.0.4.x if
+a route has been set up via 172.16.19.13 or 10.16.19.13 (respectively, for
+the case of having two distinct hosts). The routing tests verify that
+behaviour.
+
+
+ o TFTP server and its files
+
+No test of the eCos TFTP client yet, so no details here.

+
+Some Thoughts on Automated Network Testing for eCos
+***************************************************
+
+Hugo Tyson, Red Hat, Cambridge UK, 2000-07-28
+
+
+Requirements
+============
+
+This thinking is dominated by the need for automated continuous testing
+of the StrongARM EBSA-285 boards, which have two ethernet interfaces.
+We also have some needs for ongoing eCos network testing.
+
+ o TCP testing: move a large amount of data, checking its correctness.
+ (with several streams running in parallel at once)
+
+ o UDP testing: similar but using UDP.
+
+ o TFTP testing: an external server, from a choice of LINUX, NT, SunOS, and
+ another EBSA board, get from the target some files, of sizes 0, 1, 512,
+ 513, 1048576 bytes. (with several streams running in parallel at once)
+
+ o TFTP testing: put to the target some files, ....
+
+ o TFTP testing: the target tftp client code does the same, getting and
+ putting, to an external server.
+
+ [ All that TFTP test makes explicit testing of UDP unneccessary; UDP
+ testing would need sequence numbers and so on, so we may as well use
+ TFTP as the implementation of that]
+
+ o FTP test: we have a trivial "connect" test; continue to use it.
+
+ o Performance testing: TCP_ECHO, TCP_SOURCE, TCP_SINK programs work in
+ concert to measure throughput of a partially loaded target board.
+ Source and Sink apps run on an external host.
+
+ o Flood pings: the target floods the hosts on its two external interfaces
+ whilst they flood it. This is left going for a long time, and store
+ leaks or crashes are checked for.
+
+Orthogonally to these "feature tests" are requirements to run these tests
+with and without these features in combinations:
+
+ o The "realtime test harness" operating - it checks interrupt latencies
+ and so on. This is written and works.
+
+ o Booting statically, via bootp, via DHCP statically/leased on the two
+ interfaces in combination.
+
+ o Simulated failure of the network, of the kinds "drop 1 in N packets",
+ "drop all for 0 < random() < 30 Seconds" and the like. Corrupted
+ packets being sent out by the target, also!
+
+Needs
+---------------
+
+We have some other requirements:
+
+ o Support testing of other net-enabled targets!
+
+ o Run tests at a reasonable rate, so do NOT require a reboot of, say, a
+ LINUX host every test run to reconfigure the network environment.
+
+ o Feasible: do NOT require anything too complex in terms of controlling
+ the network environment.
+
+ o Do not use too many machines. The farm is full already.
+
+
+Other Goals
+-----------
+
+These are some ideas that are useful but not strictly necessary:
+
+ o Re-use/work-with the existing test infrastructure
+
+ o Provide the sort of results information that the existing test
+ infrastructure does.
+
+ o Work with standard testing *host* computers of various kinds.
+
+ o Support conveniently debugging these test examples at developers' desks
+ - not just in the farm.
+
+
+Details
+=======
+
+Because of the flood pinging and malformed packet requirements, the target
+boards need to be on an isolated network.
+
+The target board's two interfaces need to be on distinct networks for the
+stack to behave properly.
+
+
+
+Strategy
+========
+
+I believe we can implement everything we need for the host computers to do
+using a daemon or server, (cf. the serial test filter) which sits on the
+host computer waiting to be told what test we are about to run, and takes
+appropriate action.
+
+Note that this does work even for situations where the target is passive,
+eg. being a TFTP server. The target simply "does" TFTP serving for a set
+period of time - or perhaps until a cookie file exists in its test file
+system - and then performs a set of consistency checks (including on the
+state of the test FS), thus creating a PASS/FAIL test result. It can also
+periodically run those checks anyway, and choose FAIL at any time.
+
+But who tells the host daemon what to do? The target does, of course.
+That way, the host is stateless, it simply runs that daemon doing what it's
+bid, and does NOT ever have to report test results. This has enormous
+advantages, because it means we gather test results from what the target
+said, and no other source, thus minimizing changes to the farm software.
+It also means that to add a new test, we can asynchronously add the feature
+to the test daemons of that is required, then add a new testcase in the
+usual manner, with all the usual (compile-time) testing of its
+applicability as usual.
+
+Network Topology
+----------------
+
+The idea is that we can initially have a setup like this:
+
+ house network <---> [net-testfarm-machine] serial -------+
+ |
+ serial
+ house network <----> eth0 [LINUX BOX] eth1 <---> eth0 [ EBSA ]
+ [ dhcpd ] eth2 <---> eth1 [ ]
+ [ tftpd ]
+ [ ftpd ]
+ [ testd ]
+
+for developing the system. Testd is our new daemon that runs tcp_sink, or
+tcp_source, or a floodping, or does tftp to the target (rather than vice
+versa) as and when the target instructs it. The target can report test
+results to the net-testfarm-machine as usual, but with bigger timeouts &c
+configured in the test farm.
+
+This system can then be generalized to
+
+ test-server1 test-server2 test-serverN
+ eth0 eth0 eth0
+ | | |
+ | | |
+ eth0 | |
+ target1 target4 targetM
+ target2 target5 targetM+1
+ target3 target6 targetM+2
+ eth1
+ |
+ |
+ test-server11
+
+where target1,2,3 have 2 ethernet interfaces and the others have only one.
+
+And further, provided the testd protocol supports targets choosing one
+server from many which offer service, which would be a good thing:
+
+ test-server1 test-server2 test-serverN
+ eth0 eth0 eth0
+ [LINUX] [Solaris] [NT4.0]
+ | | |
+ +----------------------+------------------------+
+ | | |
+ eth0 | |
+ target1 target4 targetM
+ target2 target5 targetM+1
+ target3 target6 targetM+2
+ eth1
+ |
+ +-----------------------+
+ | |
+ [LINUX] [NT4.0]
+ test-server11 test-server12
+
+which would IMHO be a good thing IN ADDITION to a completely partitioned
+set of test network as above. The partitioned set of test networks is
+required also because we need to test all of:
+
+ Target asks for BOOTP vs. DHCP -X- Server does only BOOTP vs. DHCP
+
+in combinations on the different interfaces. Simply setting up servers
+that way statically is best, rather than trying to script controls for
+servers that have them offering bootp one minute and DHCP the next.
+
+
+Test Farm
+---------
+
+Orthogonal to the network topology, the network test farm is connected to
+all these targets in the usual manner by serial lines. That way the tests
+can run and busy/cripple that local network without affecting the house
+network *and* without affecting the debug connection, and with the
+advantage that tests net traffic can interfere with each other, providing a
+diverse network environment for testing, rather than a quiet net.
+
+For testing with GDB connection over the network, which is desirable, I
+suggest either keeping those machines separate, or having the farm's
+connection into the test-net be via second interfaces fitted to the server
+machines.
+
+Otherwise, it's a standard test farm, which knows to choose only from a
+special set of perms, and which has waaay longer timeouts.
+
+
+Test Cases
+----------
+
+In this way, tests of the form "make an external machine do tftp to the
+target board" are implemented by means of a standard eCos test case, which
+requests that action from a server, then waits for it to be told AOK or
+just for a certain time, and reports as such to the test farm as usual.
+
+These special tests are only compiled in certain perms.
+
+Those same special perms select between the various initialization options
+required also: DHCP or BOOTP or static initialization, and so on, in the
+usual manner.
+
+
+Implementation
+--------------
+
+Just a quick note on this: DHCP has a lot of the properties we want for the
+test protocol. We should take a copy of that and use different port
+numbers, re-use a lot of the code, since server code is also available.
+
+Or something simpler; none of this seems especially challenging.
+
+
+That's all for now.

+// Purpose: Automated testing of the eCos TCP/IP Network Stack
+// Description:
+
+// This .inl file defines routines which send /orders/ to the server
+// running on the host machine who served us DHCP, and receive
+// /results/ from the same machine or machines.
+//
+// autohost_tell() sends the order to an app "awaitorder" which feeds
+// the order into obey.sh which obeys the order, for example, running
+// some tftp sessions to exercise the tftp server.
+//
+// The /orders/ must come from a predefined list, to match the
+// selection which obey.sh is expecting, for example "TFTP_SERV_GET"
+// which has further parameters <target> <timeout>. Additional
+// parameters are added/manipulated by obey.sh which then invokes a
+// relevent script (tftpget.sh) to do the test.
+//
+// The test script's output is returned to us, and is collected by
+// autohost_getresults() which runs in a high-ist prio thread. It
+// prints the output, which is expected to match the traditional eCos
+// PASS:<happy> FAIL:<eek!> sort of format, so that the test farm can
+// collect these messages from the testcase output, without any direct
+// connection to the server.
+//
+// autohost_init() simply starts the autohost_getresults() thread.
+//
+// The predefined list of orders is *not* defined here or anywhere
+// else besides obey.sh which does a switch statement for them, to
+// make it easier to extent; similarly the params each order takes are
+// not centrally recorded either. It is however a convention that the
+// word following the /order/ is our own IP address.

+// eth0-host -> 10.0.3.1 and maybe others
+// eth1-host -> 10.0.4.1 and maybe others
+// 10.0.5.x should not exist

+// These additional addresses can exist as extra loopback addresses, lo0:0,
+// lo0:1 and so on in a linux box.
+//
+// We want to ping all of the following:
+//
+// eth0-host should always work
+// eth0-host+32 not expected to work
+// eth1-host should always work
+// eth1-host+32 not expected to work
+// www.cygnus.com should always work if default gw is correct
+// 10.0.3.1 should only work if route via eth0-host is added
+// 10.0.3.99 might work if route via eth0-host is added
+// 10.0.4.1 should only work if route via eth0-host is added
+// 10.0.4.99 might work if route via eth0-host is added
+// 10.0.5.1 should never work
+// 10.0.5.99 should never work
+//
+// So we test those places in the following contexts:
+//
+// 1) No special routing added
+// 2) route via eth0-host to 10.0.3.x is added
+// 3) route via eth1-host to 10.0.4.x is added
+// 4) Both routes are added
+//
+// and check for correct operation and correct failure in all cases.
+//
+// Because of the time taken, these are separate test cases which include
+// this INL file after making suitable #defines.
+//
+// All the while, the hosts shall ping us, and when all is going we loop for
